ANCHOR FOR ANCHORING VESSELS.

SPECIFICATION forming part of Letters Patent No. 352,481, dated November9, 1886,

Application filed June 9, 1886. Serial No. 204,570. (No model.)

To all whom it may cancer-m Be it known that I, Banners D. MONTAGUE, acitizen of the United States, residing at Hopedale, in the county ofWorcester and State of Massachusetts, have invented a new and usefulImprovement in Anchors and Modes of AnchoringVessels, (for which Ihavenot obtained a patentin any country,) of which the following is aspecification.

My invention relates to an improved mode of anchoring vessels, andembodies an anchor of improved construction, together with certaindetails in construction and combination, hereinafter fully set forth.

In describing my invention in detail reference is made to theaccompanying drawings, which form a part of this specification, inwhich- Figure 1 shows a central longitudinal vertical section of alight-ship at anchor, illustrating my invention. Fig. 2 is an elevationof my improved anchor, showing the flukes spread out. Fig. 3 is anelevation of the same, showing the flukes folded up close to theanchor-shank. Fig. 4. is a bottom view of the anchor, illustrating it asconstructed with three flukes; and Fig. 5is an enlarged view showing aportion of the anchor-shank, hawser, and leading-chains.

Similar letters indicate corresponding parts in all the figures.

A is the anchor-shank, provided at its upper end with the hawser-ring B,in the usual manner, and at its lower end with the flukes C. Theseflukes are pivoted to the anchorshank by the pivotal bolts aindependently of each other, each fluke being adapted to be folded upagainst the anchor-shank separately from the others, as shown in Fig.-3. The flukes at their inner ends are provided with the, shoulders b,which, coming against the anchor-shank,-prevent the flukes from openingbeyond a given distancefor instance, that shown in Fig. 2. Each flukehas a leading chain, e, attached to its outer end, as shown at it. Theseleading-chains pass through the rings (1, attached to the anchor-shank Aat a point preferably just above where the points of the folded flukestouch said anchor-shank, as seen in Fig. 3. The leading-chains e arejoined together at 9, above the ring B, and thence continue somedistance as asingle leading-chain, f, which is attached to the hawser Fat 71. pass above the deck when the open anchor The leading-chainf islong enough to p hangs suspended just below the bottom of the i chain fis above the deck, at which time the open anchor hangs just below thekeel, the

leading-chains e hanging loosely, as shown in Fig. 2. The leading-chainf is now hauled up, and this draws up the leading-chains e, attachedthereto, through the rings d, which operation simultaneously draws allthe flukes 0 close up to the anchor-shank, which they closely hug aslong as the leading-chain f is kept taut. The folded anchor is nowreadily raised to the deck through the hawser-pipe E.- To anchor thevessel this operation is simply reversed. The folded anchor is passeddown through and below the hawser-pipe, the leading-chain f is then letgo, and the flukes of their own weight fall open, as shown in Figs. 2and 4. WVhen the bottom of the sea is reached and the anchonshankfalls'over, the lower flukes dig into the bottom and hold thevessel,whether the upper flukes remain spread out or not.

By constructing the anchor in the manner described the hawser-pipe maybe made much smaller in diameter than would be necessary were a rigidanchor used.

Some advantages of anchoring vessels amidships in the manner describedmay be stated as follows: The vessel at anchor will ride on the crest ofwaves without shipping water. It may be anchored in water of unlimiteddepth and will be held steady by the center in case of a storm, insteadof being drawn under by "the bow, as is often the case when vessels arechains e, attached to said flukes, and the lead- ,ing'chains e and atthe other to the hawser F,

anchored in the ordinary way from the bow. Thus much greater safety isattained. Again, when sailing or drifting in a gale, the anchor can bereadily dropped down any desired distance below the keel amidships, andwill thus answer as a drag or low ballast to steady the ship and keepher upright. Furthermore, telegraph-cable light-ships provided with thismode of anchoring will outride any storm, and in case of the approach ofan iceberg or other similar source of danger can readilybuoy theircables, slip their moorings, and sail away until the threatened dangeris passed, and then return to anchor again.

What I claim as my invention is 1. The anchor-shank A, provided with theflukes G, pivoted thereto independently of each other, in combinationwith the leadinging-chain f, attached at one end to saidleadsu'bst-antiall'y as-described. 9

2. The combination of the anchor-shank A,

provided at one end with the ring B, the hawser F, attached to saidring, the flukes C, pivoted to the opposite end ol said anchor-shankindependently of each other, the guide-rings (I, attached to saidanchor'shank, and the leading-chains 6, attached to the outer end ofsaid flukes and passing through said guiderings d, whereby said fiukesmay be drawn close up to said anchor-shank, substantially as set forth.

3. The vessel D, provided with the hawserpipe E, passing through thebottom of said vessel amidships, the hawser F, the anchor consisting,essentially, of the shank A and independently-pivoted flukes O, theleadingchains 0, attached to said flukes, and the leading-chain f,attached to said leading-chains e 0 and to said hawser F, the wholecombined and operating substantially as described.
